Hello from Estonia

Hi, I'm Kristjan, I live in Estonia and I'm currently building a bike with Yamaha DT125R chassis and Qingqi QM200GY engine. It will be used on both motocross and enduro tracks in future...
Everything started when a friend went for a ride with my Yamaha and seized the engine. He had the QM200 in his KX125 frame before, because the original Qingqi chassis wasnt very good, the rear wheel broke apart and ruined everything.

Iv'e previously had some Riga mopeds, three 350cc IZH Planetas, Motorhispania Furia with full MK Pro Race 70 engine, 2 Yamaha TZR125R italian models, a Honda MTX80 which was always broken, Aprilia AF1 125 Futura, Gilera MX-1 125 (I regret selling it, could have been a nice project bike), Suzuki AY-50 Katana scooter, three Kawasaki AR125-s (I love those, really cool bikes if u ask me), Yamaha YZ80, some kind of Qingqi 50cc moped...

Besides the Yamaha DT I also have a Honda Dio scooter.

I found this forum when I was searching Google, trying to find out if anyone has made his QM200GY go faster and what was done to make it happen. :D So, any advice is welcome! :) I'm more familiar to two strokes than fours.

Ex.,
Welcome to MCM.
Interesting project you have going on. Some photos would be nice.

Dear Kristjan,

Welcome to the board, and please feel free to ask specific questions about your retrofit. I don't recall anyone trying such a project, but you may find answers by searching the site. There's a ton of info about the 200GY, and a lot of expertise among our members.

Good luck with it, and, yes, do post some pictures of your work in progress -- and of your rides there in Estonia.

Estonia!! How cool is that!

cheers

Here's the modifed frame, almost finished.

And this is prettty much what it is going to look like:

Unfortunately the QM200 engine does not have kickstart, which I'd like much more than the electric one. But at first I need to make it run, then complain. :icon10:

Once again, this is not China-related, but since we are on the subject of Estonia, and motorcycles, cast your gaze at this -- from Renard Motorcycle of Tallinn!!

euphonius, don't you think you're watching too much moto' porn for one day? Have you considered counseling ?

Welcomed Kristjan, you've found the right forum .. welcome aboard.

To be honest I was not expecting you to talk about that one. Renard is a nice piece of art but not exactly what I would like to ride. If I would make a motorcycle, I'd probably come up with something more usual and practical.

I also put some pictures of my project in my last reply above, have a look. :)

Dear Extinction,

Thanks for the glimpses of your project. Nice work, and a nice shop as well. The Renard is indeed a piece of art, but yours is an impressive piece of practical craftsmanship and pride. Touché!

As for the QM200GY engine and power train, there's definitely expertise in this forum. Any specific power-boosting mods that you are considering?

cheers

i would love a workshop that big to work in i see your doing it the right way working on bikes and beers on the side for abit of relaxing

Welcome to the forum!

Welcome to here! :thumbsup:

Have you looked into Suzuki for tips? The Qingqi 200 engine is based on the Suzuki 200cc engine as Qingqi is the OEM for Suzuki's small engines. We have had several discussions on what people did to their Qingqi bikes--look around in the search for the brand name (in the US) 'Qlink XF 200' as that is who imported the bikes to the US. Other regional brands' names should show up, too. :riding:

I have read a lot of these disscussions for now and keep doing it. I have also thought about replacing or grinding the camshaft, but there is'nt very much info on that.

The workshop belongs to a friend of mine, there are a lots of bikes besides mine to be honest. Too bad I can only work on my machines on weekends because of school.

I have the frame and swingarm painted already and the bike needs just few more things to be ok, although plastics still need some work to get them look ok. I'll try to keep in mind not to forget my camera at home when the bike is ready to ride, I'd like to take some pics while it is shiny and "new" with no dirt on it.:icon10:

Well, I havent got enough time to do the plastics, our track isnt wet any more and I needed to ride. Until the gearbox broke. I have ordered new transmission and I'm also waiting for a spare engine so it will soon be running again.

Some pics of the project:
Attachment 4031Attachment 4032

The engine is a beast with straight-through exhaust and rejetted carb, changing the needle improves low end and midrange a lot but I havent found any needles that will fit, the one I got was too tapered and the mixture went really rich. Will continue trying to make it go faster. I might make a new thread about my mods when I think that I have enough to show and talk about. :)

To be honest, I think that Yamaha DT125R looks way cooler with that big four stroke engine than it did with its tiny two stroke... :D

Funny because my Qlink XF200 has a kick starter.

I thought they were the same engine.

There must be different versions of it. For example, I cant use original kickstarter bits on my engine and get it work because the crankcase and clutch cover are different and the kickstart shaft cant be put in, the second shaft in the gearbox is shorter so there is no possibility to add kickstarter idle gear, and the clutch basket does not have a smaller gear behind the big one for the kickstart as well.

Basically tey are the same engines but they just have some differences between different versions. Just like automatic or manual cam chain tesioner etc. When mine is marked K166FMI, I've read about K166FML in forums and so on.
